To all 4'whom t mayconoem.

Be it known that l, ANDREW R., P AUL, a citizen of the United States, residing at Somerset, in: the county of Somerset and State of Pennsylvania, have :inventedl a new and useful Soldering-Iron, of whichl the following is a speciication.

The invention relates Solderin irons. c

The o ject ofthe present invention isto improve the construction of solderingirons and tol provide an exceedingly simple, prcesigned for the use of tinners, plumbers, metallic workers, and others, and adapted particularly for' outside `work upon roofs and other places and constructed :for using acetylene and. similar gaseous uel under pressure, and capable of developing a strong blast .of heat and of delivering the same interiorly of the head; of the soldering ironwhereby the latter is quickly heated and, is maintained at a highv temperature.;

' A further object of the-invention is lto provide a soldering iron adapted. tobe instantly converted into a blow torch. and equipped with means for throwing a. light over the end of the soldering ironhead when desired, without interfering with the operation of the heating means. l

With these` and other objects in. view the invention consists in the construction c and novel combination. of parts hereinafter fully to improvements in described, illustrated in. the accompanying drawings, and pointed out in. the claims hereto appended, it being understood that various changes in. form, proportion, size and minor details of construction,` within the scope of the claims may be resorted to without departing from'the spiritor sacri.- iicing any of the advantages of the invention. c

In the drawing: Figure 1 is a side elevation of a soldering iron constructed in accordance with thisinvention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a.y transverse sectional view on the line 3-3 of Fig. 2. Fig. 4 is a. similar view on the line 4 4 of Fig. 2. Fig. 5 is a side elevation of the tool, the head of the soldering iron being removed to convert it into a blow torch.

Like numerals of. referencedesignate corresponding. parts in all, the figures of the drawings.

In the accompanying drawing, in which is illustrated the preferred embodiment of the I invention, the soldering iron comprises in its construction ahollow handle 1 secured onl the inner portion of a` tubular stem 2,` constituting a gas supply pipe and designed to be connected with a gas tank (not shown),

or any other suitable source of gaseous fuel supply, the tool being designed especially for the use of such fuel. The tubular stem extends inwardly or rearwardly beyond the handle 1 and its inner or rear end 3 is provided with exterior annular grooves or corrugations and is adapted to receive one end v o f a rubber tube 4 or other fiexible connection for connecting the soldering iron with Y the prest-o-ll-te or other gas tank. The outer Patented Mar. ze, 1915.

portion ofthe tubular stemis tapped at a point slightly beyond the handle 1 to receive a lateral branch 5 which is connected by a T-coupling 6 with a longitudinal tube 'Z carrying a burner tip 8 of the ordinary construction. `The burner `formed bythe longitudinal tube' 7 and the tip 8 is adapted to throw a strong lightA over the head 9 of the soldering iron, and enables the latter to be conveniently and accurately used in dark corners and various other 'places where a light is necessary, and where a candle is ordinarily employed for such purpose. The coupling 6 is equipped with a suitable valve 1.0; for controlling the iiow of gas to the said burner., The tubular stem2 has a threaded portion 11 adjacent to its front end .12 to screw into an interiorly threaded neck 13 of a cup-shapedsupport 14. The outer end12 of the tubular. stem or supply pipe receives a suitable tip 15 which discharges the gas into a-burner tube .18 having a. greater diameter than the discharge orifice of the tip 15, and provided with. perforations 19 arranged at intervals and, forming lateralair inlet open.

ings which permit the air to be drawn or sucked into the burner tube by the gas passing through the same. This causes a mixing of the air and gas at the point of ignition and results in perfect combustion, producing a blast and a llame and enabling the device to be'used as a blow torchwhen the head of the soldering iron is removed.

The tip- 15, which is removable, is adapted, when necessary, to be readily renewed,-

but instead of employing a tip of the particular form showmthe supply tube may bel provided at its :outer en d with `any other form of jet aperturev for discharging the gaseous. fuel into the burner tube. The

l the same.

inner end 20 of the burner tube is exteriorly threaded and screws into the inter1orly threaded neck 13 of the cup-shaped support 14, and the outer end 12 ofthe combined tubular stem and supply pipe is reduced and extends into the inner end of the burner tube, presenting a smooth exterior face to The inner end of the burnery tube is spaced from the shoulder 21, formed by reducing the outer end of the stem 2, and the said spacing of the burner tube and the shoulder permits a relativevadjustment of the parts, in order to enable the tip to be arranged in proper position with relation to the burner tube. rlhe threaded engagement of the burner tube and the combined stem and supply pipe with the neck of the cup-shaped support retains the said parts in their adjustment.

The sides or walls of the cup-shaped support arel cylindrical and are spaced from the burner tube 18 topermit ready access of air to the apertures 19, and the said support receives a coupling sleeve 22 which carries 'the head 9 of the soldering iron. The sleeve 22 consists of inner and outer annular portions and longitudinal connecting portions whichare spaced apart to provide opposite openings 23 forthe admission of air to the burner tube- 18 to support combustion. IThe burner tube 18 extends beyond the cupshaped support and its outer portion'isexposed at the side openings 23 of the sleeve 22. The inner annular portion of the sleeve 22' is provided with opposite L-shaped bayonet slots 24:l consisting of a longitudinal entrance 'branch and an inner transverse branch and adapted to engage opposite projeetions 25 mounted on the cup-shaped support. By this construction the sleeve 22, which carries the soldering iron head 9, is detachably interlocked with the cup-shaped support and may be easily and quickly applied thereto and removed therefrom to convert the instrument into either a soldering iron or a blow torch.

The soldering iron head 9, which is provided with a tapered outer portion, has its inner end 26 exteriorly recessed and secured within the outer annular portion of the coupling sleeve 22 by a screw 27 or other suitable fastening device. The inner portion of the head 9 is provided with a chamber 28 tapered toward the outer end ofthe head 9 and adapted to present a relatively large amount of heating surface to the flame of the blow torch or heating burner of the soldering iron.- The said chamber 28 is provided with lateral outlets 29 extending through the walls of the chamber and registering with openings 30 in the outer annular portion of the sleeve 22. In the operation of the soldering iron the gas from the supply tank is discharged directly into the burner tube and does not mix with the aisance- 'terminates short of the cup-shaped portion of the support and is not in the way when the tool is used either as a soldering iron or a blow torch.
